REWERSE - REasoning on the WEb with Rules and SEmantics
The objective of REWERSE was to establish Europe as a leader in reasoning languages for the Web by
- networking and structuring a scientific community that needs it, and by
- providing tangible technological bases that do not exist today for an industrial software development of advanced Web systems and applications.
Impact
The community networked and structured by REWERSE
- developed a coherent and complete, yet minimal, collection of inter-operable reasoning languages for advanced Web systems and applications;
- tested these languages on context-adaptive Web systems and Web-based decision support systems selected as test-beds for proof-of-concept purposes;
- brought the proposed languages to the level of open pre-standards amenable to submissions to standardisation bodies such as the W3C.
Main innovation
For the full exploitation of the Semantic Web it is necessary not only to describe meta-data but also provide languages and methods to query and to automatically reason over these data, i.e. to derive new not explicitly stated information from existing data using various forms of rules.
REWERSE developed a format, or markup, for rule languages, approaches to specifying policies, i.e. high-level specifications for complex Web systems, methods for composing and typing Web rule and query languages, a query language for Web and Semantic Web data, rule-based approaches to specifying reactive behaviours of Web systems. In addition, REWERSE developed methods for expressing and processing temporal and location data, semantic approaches to Bioinformatics, and methods for personalisation.
Result
The focus of REWERSE is the definition of languages and support tools for reasoning on the Web and the application of these technologies in different application domains. In its first months REWERSE has defined requirements and base components for the different technologies accompanied by thorough state-of-the-art surveys. At the end of year one use cases for the respective technologies have been defined that all require rules and reasoning for satisfactory realisation. In year 2 REWERSE has been implementing first prototypes of the respective technologies. More concretely, the languages, use-cases, prototypes and applications that are worked on concern: rule markup languages, policy specification, typing and composition of rules, querying and transformation, reactive behaviour and evolution of information, geotemporal and geospatial reasoning, bioinformatics data integration and personalisation on the Web.
These research results can be followed here; in particular the results are documented in the deliverables and research publications . At month 20 REWERSE members have contributed to over 200 internationally reviewed publications showing that REWERSE's focus is perfectly targeted to current research needs. Demonstrations of prototypes developed within REWERSE are available here.
REWERSE has organised three major dissemination events in year 2: the first "Reasoning Web" Summer School (July 2005, Malta), the industry awareness event "Semantic Web Days" (October 2005, Munich) and the research workshop "Principles and Practice of Semantic Web Reasoning" (PPSWR'05) (September 2005, Dagstuhl) (More details).
Since October 2005 REWERSE holds a consortium membership in the W3C and has a dedicated standardisation task force. REWERSE members actively participate in standardisation activities, in particular in the W3C Rule Interchange Format Working Group and in the W3C Semantic Web Health Care and Life Sciences Interest Group (HCLSIG). Details of the standardisation activities are available here.
